Trademarks Preface Read This First About This Manual The evaluation modules (EVMs) (TPS60120EVM-142 and TPS60130EVM-143) for the new Texas Instruments (TI) charge pump devices TPS60120 and TPS60130 help designers to evaluate the devices. The TPS60120 and TPS60130 charge pumps (also called switchedcapacitor dc/dc converters) are regulated, high efficiency dc/dc converter. With these EVMs it is possible to evaluate the performance of the devices.

Chapter 1 Introduction The Texas Instruments (TI) TPS60120 and TPS60130 charge pumps are regulated, high efficiency voltage converters. The TPS60120 delivers an output voltage of 3.3 V. The maximum output current is 200 mA for 2 V to 3.6 V, and 100 mA for 1.8 V to 2 V. The TPS60130 has an output voltage of 5 V. The maximum output current is 300 mA for an input voltage from 3 V to 5.4 V, and 150 mA for 2.7 V to 3 V. Both devices work either as voltage doublers or, in 1.

Layout of the EVM 2.1 Layout of the EVM Figure 2–1 and Figure 2–2 show the placement of the components and the layout of the EVM. The components and all signals are exclusively placed on the top layer of the PC board. To provide optimal performance, the bottom layer is a solid ground plane (only interrupted by some vias). Figure 2–2. Placement of the Components Figure 2–3.
Setup of the EVM The space required for the IC and the capacitors on the EVM is approximately 15 mm × 16 mm = 240 mm2 2.2 Setup of the EVM For proper operation of the EVM, follow these steps: 1) Make sure that the ENABLE input is either properly jumpered or connected to an external source. 2) Connect a load to the output (between GND and Out) TPS60120: > 16.5 Ω or 0 mA to 200 mA (VIN between 2 V and 3.6 V) > 33 Ω or 0 mA to 100 mA (VIN between 1.8 V and 2 V) TPS60130: > 16.
